Answer:

175

Step-by-step explanation:

The sample size n in Simple Random Sampling is given by

$\bf n=\frac{z^2s^2}{e^2}$

where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation.

Replacing values

$\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175$

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000

Answer:

Graph A

Step-by-step explanation:

$y = {x}^{2} - 6x - 7 \\ plug \: y = 0 \\ {x}^{2} - 6x - 7 = 0 \\ {x}^{2} - 6x + 9 = 7 + 9 \\ (x - 3)^{2} = 16 \\ (x - 3) = \pm 4 \\ x = 4 + 3 \: or \: x = - 4 + 3 \\ x = 7 \: or \: x = - 1$

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.
